退出时，OpenCV程序使linux崩溃（使用cvtColor）

Question

I've made a working application using OpenCV that crashes linux mint, after the program is finished (return 0;).

I've narrowed the code down to the snippet below. When the function cvtColor is used, the program crashes. While the code is running, nothing weird is going on and cvtColor is doing it's job.

I'm not ac/c++ programmer, I don't even know where to look further to what causes this or how to find something to help me google for a solution.

Can someone point me in the right direction?

The version of OpenCV: 3.0 Running on: 3.11.0-12-generic #19-Ubuntu x86_64 x86_64 x86_64 GNU/Linux

#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

#include <string>

using namespace std;
using namespace cv;


int main( int argc, char** argv )
{
    Mat frame1;
    Mat grayImage1;

    frame1 = imread("lena.jpg");

    cvtColor(frame1, grayImage1, COLOR_RGB2BGR);

    return 0;
}

Answer 1

OpenCV 3.0似乎仍处于Alpha阶段，因此我建议您尝试使用稳定版本进行相同的操作，并检查是否存在相同的问题。

Answer 2

I don't know if this is causing the crash, but a potential problem is the conversion from RGB to BGR.

You probably wanted to execute COLOR_BGR2RGB instead, since the data is originally stored as BGR .
